Title: Improvements in the production of porous masses and shaped articles from polymers
IPC: C08J9/06
Filed: 1950-10-30
Abstract: Porous masses or porous shaped articles are produced by dissolving or homogeneously dispersing a raising agent, capable of splitting off gas, in a monomeric polymerizable ethylene derivative, polymerizing the resulting solution or mixture at room temperature or moderately elevated temperature under such conditions that no decomposition of the raising agent takes place, until a solid product is formed, and thereafter heating the product to a temperature at which the polymer becomes plastic and the raising agent decomposes.  Ethylenic monomers specified are styrene and methyl methacrylate, and mixtures of these substances with vinyl esters, acrylic acid esters, and maleic acid esters. Raising agents specified are ammonium carbonate and bicarbonate, azodi - isobutyronitrile, azo - di - hexahydrobenzonitrile, and diazoaminobenzene.  When the raising agent is one which gives rise to free radicals under mild polymerization conditions additional polymerization catalysts may be dispensed with, though the use of peroxide catalysts, such as benzoyl peroxide, is preferred.  The monomers may have dissolved therein prior to polymerization other highly polymerized substances such as polyisobutylene, polystyrene, polyacrylic esters, polymethyl methacrylate, polyvinyl esters, and interpolymers from the monomers of these polymers, cellulose derivatives and alkyd resins.  The polymers containing the raising agents may be comminuted, introduced into a mould, and then heated to decompose the raising agent.

Title: Improvements in automatic couplings for railway vehicles
IPC: B61G5/08
Filed: 1930-09-05
Abstract: 345,606. Automatic couplings for railway vehicles. SENGER, A., 31, Lunkerhohl, Iserlohn, Westphalia, Germany. Sept. 5, 1930, No. 26572. [Class 103 (v).] Relates to automatic couplings for railway vehicles of the kind in which the draught coupling is effected by means of resiliently supported horizontally movable hooks with collapsable ends or beaks and the train-pipe coupling by means of interengaging cones and funnels. According to the invention, the collapsable ends 17 of the hooks 7 are retained in their coupling position or released therefrom by means of slides 12 actuated from the sides of the vehicle through linkages 14, 15 and operating handles 21. In the construction shown the ends 17 are pivoted at 18 in forks 19, Fig. 4, and, by entering the spaces 23 between the limbs of the forks prevent disengagement of the hooks by any relative vertical displacement. The shanks 7 of the hooks are pivoted to supports 3 pressed forwardly by springs 4 and are deflected laterally, when a coupling is being effected, against the pressure of laminated springs 10. The interengaging funnel and conical members 37, 38 with which the pipes 36 are associated are mounted on blocks 35 adapted to swivel on vertical pivots 34 on supporting plates 32, which in turn are slidably arranged on rods 33 carried by transversely slidable elements 27 movable in vertically guided slides 25, springs 26, 28, Fig. 7, normally centralizing the elements 25, 27. By this arrangement the funnels and cones are capable of displacement in any direction so as to ensure their correct alignment with each other, while spring-controlled levers 30, Fig. 5, hinged at 29 to the slides 27 are employed to hold the supporting-plates 32 in an advanced position.

Abstract: 872,762. Adjustable stands. TOMADO N.V. Aug. 5, 1959 [June 22, 1959], No. 26669/59. Class 128. An adjustable stand for a dish, bowl &c., comprises two halves which can be slid towards or away from each other. Each half is provided with a handle 1, a pair of feet 2 and a pair of parallel bars 3, 4. Each bar is slidingly enclosed, together with the corresponding bar of the other half, in a sleeve 5 provided with a longitudinal slot 6, into which extend projections 8 and 9 on the bars. The slot is narrowed, at its ends, to form abutments 7, which, normally, make contact with the projections and thus limit the movement of the two halves away from each other. When the bars are given a slight twist within the sleeves, the projections can pass through the ends of the slots to allow the two halves to be disconnected.

[Also in Division F2] A piston rod 10 of a shock absorber assembly is connected to a piston 26 by inserting a tubular extension 14 (Fig. 3, not shown) of the rod in a central aperture in the piston and pressing the extension outwardly by means of a grooved forming electrode 60 to lie in a recess 70 of the piston, as shown. A heating unit 58 provides a current between the forming electrode 60 and an electrode 62 for heating the extension as it is deformed, an initial radial clearance between the extension and piston minimizing heating of the piston (with its insert 36 of plastics material). Further heating may be applied after the forming step to anneal the connection, the subsequent cooling of the piston rod tending to produce a prestressed connection. The axially extending lip 28 of the piston is turned over by a roller to retain an outer cap 52, Fig. 6 (not shown), in the completed assembly.

Condensers 27, 28, 29 are connected either across each phase of the distribution system as shown or directly across the primary or secondary windings of the supply transformers, which condensers determine frequency, and, by discharging at the moment when one valve of a pair begins to pass current, cause a momentary reversal of the potential applied to the other valve of the pair. Condensers are also connected between the grid and cathode of each valve in order to smooth out fluctuations in the grid current.
